cfetoolgraph – create graphs from a cfetool database

Synopsis

cfetoolgraph name [–path|-p directory name] [–daily|-d] [–weekly|-w] [–yearly|-y] [–timestamps|-T] [–resolution|-r] [–help|-h]

Description

The cfetoolgraph command dumps graphs of averages for visual inspection of the normal state database. The files are in a format viewable by "gnuplot" or "xgmr" or other graphical plotting program.

The command generates three or four files in a subdirectory of the database directory with a name beginning with either "daily", "weekly" or "yearly", then "-", then either "snapshot" or the current time, if the -T option is used. The files are named "average", "stddev", and "graph". The "graph" file contains both the averages and standard deviations, useful for plotting with error bars.

If a histogram file is present, a fourth file named "distr" will also be created, plotting the distribution of fluctuations about the mean value.

If the -d, -w and -y options are all omitted, the default is to only graph the weekly database.

Options

–path|-p directory name

The directory in which the database specified by name can be found.

–daily|-d

Graph the daily averages database.

–weekly|-w

Graph the weekly averages database.

–yearly|-y

Graph the yearly averages database.

–timestamps|-T

Time-stamp the output filenames with the current time, in order to give a unique name.

–resolution|-r

Generate high resolution data (), instead of averaging data over periods of one hour to generate simpler and smoother graphs.

–help|-h

Prints a short help message and then exits.

Example

 % cfetoolgraph temperature --path /my/path --resolution

Create graph files of the weekly database in high resolution in the "/my/path/temperature/weekly-snapshot" directory.
